A turntable $($disk$)$ of radius $r=25\mathrm{.}5cm$ and rotational inertia $0\mathrm{.}395kg*m^2$ rotates with an angular speed of $2\mathrm{.}92ra\frac{d}{s}$ around a frictionless, vertical axle. A wad of clay of mass $m=0\mathrm{.}254kg$ drop. onto and sticks to the edge of the turntable. What is the new angular speed of the turntable?

$2\mathrm{.}57$

Your response is within $10\%$ of the correct value. This may be due to roundoff error, or you could have a mistake in your calculation. Carry out all intermediate results to at least four$-$digit accuracy to minimize roundoff error. rad$/$s
